BRAKE-BAND ANCHOR BRACKET.

Application led Ju1y18, 1924. Serial No. 726,668.

To all fui/0m t may concern.'

Be it known that I, ROY C. PARKS, citizen of the United States, residing at Detroit, county ci' lVayne, State of Michigan, have invented a certain new and useful Improvement in Brake-Band Anchor Brackets, and declare the following to be a full, clear, and eXact description oit the same, such as will enable others'skilled in the art to'which it pertains to make and use the saine, reference being ha-d to the accompanying drawings, which form a part of this specification.

My invention relates to anchor-brackets for the brake bands ot motor driven veh'icles, shown in the accompanying'drawings and more particularly' described inthe tollowing specification and claims.

The primary object vci this invention is to construct an inexpensive and effective anchor bracket formed ot sheet metal by suit-- able punching and Jforming dies, in which the projecting arm of the anchor bracket connected to the brake band by the usual overlapping loop member is reinforced by a metallic inlay riveted or otherwise secured thereto between the' flanged walls of the arm-additional strength and stillness is thus added to the latter arm. The metallic inlay secured to the arm of the bracket is tapped to receive the end of a bolt connecting it with the brake band,-the bracket arm being bored to forni a counterbore surrounding the tapped hole in the inlay to receive the end of a spring sleeved upon the bolt for freeing the brake band 'from the brake drum 'when the brake mechanism is released.

An inexpensively constructed device designed with a view to intensive production is thus provided, the tensile strength of which is greatly 'in excess of other anchor brackets now upon the market.

lVith the 'foregoing and other objects in view which will appear as the description proceeds the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes may be made in the precise en'ibodinlent et' the invention herein disclosed without departing from the spirit oi' the saine.

In the drawings accompanying this specitication:

Figure 1 is a 'fragmentary end elevation of the rear axle of a motor vehicle with parts broken away and in section showing the anchor bracket secured to the usual dust plate and supporting the brake band surrounding the brake drum.

Figure 2 is an end elevation oi' the bracket with its arm in cross-section, taken 0n or about line 2-2 of Figure 3.

Figure 3 is a side elevation of the bracket showing a portion of' the arm, in section to disclose the metallic inlay riveted betweenV the flanges of the bracket, tapped to re ceive a bolt by which it is connected to the brake band.

Figure 4- is a fragmentary elevation of the drum, the overlapping brake band, and the loop connecting the arm of the anchor bracket with the brake band.

Referring now to the letters of reference placed upon the drawings:

A, denotes the axle of a motor vehicle: B, a traction wheel: C, the usual brake drum: D, its dust plate fitted within the liange of the drum.

E, designates a brake band provided with the usual brake lining El.

F, indicates a loop-shaped member riveted to the brake band to receive the arm of an anchor bracket G, Constructed of sheet metal by suitable blanking and forming dies.

The bracket G comprises a flattened portion G pierced with a plurality of holes G" to receive bolts or rivets I, for vsecuring it to the dust plate D.

The flattened portion G, or the base plate of the bracket has a projecting arc-shaped extension GC connecting it with an arm G extending at right angles thereto, having side walls g, forming a channel which flares outwardly at the arc-shaped portion, connecting the arm of the bracket with the base plate--see Fig. 2.

Fitted between the channel walls of the bracket arm is a metallic inlay H, which may be riveted (7D-spot welded or otherwise secured to the bracket arm thereby increasing the strength and rigidity of the arm.

It desired the metallic inlay H may have a dove-tailed arc-shaped end H to be lodged between the side walls of the arc-shaped portion connecting the base plate with the projecting arm of the bracket.

The metallic inlay H, litted to the arm of the bracket is tapped to receive a bolt J,

extending through the loop-shaped member F attached to the brake band E, to secure the latter to the anchor bracket. Surrounding the bolt J and extending from a count'erbcre rGre in the arm of the bracket is a spring K adapted to bear against the head of the bolt, the action of the spring serving to raise the brake band from contact witli the drum when the brake mechanism is released.

While I have shown the metallic inlay with a dove-tail arc-shaped end IIa adapted to lit the arc-shaped portion of the bracketthe 'inlay may terminate short of the arcshaped portion of the bracket if desired for relatively light motor vehicles. Se also while the drawing shows the metallic inlay riveted to the arm of the bracket it may be spot welded7 or otherwise attached.

Having thus described my invention what I claim is:

Vl. A device of the character described comprising abase plate adapted for attachment to the dust plate of a brake drum, having an arm bent at right angles to the base plate of which it is an integral' part,-said arm being of channel-like form in crosssection; a reinforcing metallic inlay lodged between the walls of the channel-like arm and secured thereto, said reinforcing metallic inlay tapped to receive a bolt for connecting the arm with a brake band, said channel-arm having a bore concentric with the tapped hole in the reinforcing metallic inlay, wherein a spring may be lodged to normally maintain the brake band in released relation to a brake drum.

2. A device of the character 'described formed of sheet metal by suitable blanking and forming dies, comprising a base plate adapted for attachment to the dust plate of a brake drum, having an arm of channellike form in cross-section connected by a flaring arc-shaped portion with said base plate of which it is an integral part; a reinforcing metallic inlay lodged between the walls'of the channel-like arm and attached to the latter and having a flaring arc-shaped end conforming to the arc-shaped flaring portion connecting the channel arm with the base plate, said reinforcing metallic inlay being tapped to receive a bolt for connecting the arm with a brake band, said channel arm having a bore concentric with the tapped hole in the metallic inlay forming with the latter a socket or counterbore wherein a spring may be lodged to normally maintain the brakeJ band in released relation to a.l brake drum.

3. A device of the character described constructed of sheetmetal by suitable blanking and forming dies consisting of base alate' punched with a plurality of holes for tie passage. of rivets or bolts, whereby it may be secured to the dust plate of a brake drum; an arm of channel-like form in crosssection having a flaring arc-shaped portion connecting the channel arm with the base plate at right angles to the latter,-of which it is an integral part; a reinforcing metallic inlay lodged between the walls of the channel-like arml andriveted thereto having a flaring arc-shaped end conforming to fthe arc-shaped flaring portion of the channel arm, said metallic inlay having a tapped hole to receive a bolt for connecting the arm with a brake band, said channel arm having a bore concentric with the tapped hole in the metallic inlay forming with the wall of the latter a socket or counterbore wherein a spring may be lodged to normally `maintain the brake band in released relation to a brake drum.

In testimony whereof, I sign this specification in the presence of two witnesses.
